Pi (π) to 30 decimal places: (Word lengths are digits)Now I, even I, would celebrate
In rhymes unapt, the great
Immortal Syracusan, rivaled nevermore,
Who in his wondrous lore,
Passed on before,
Left men his guidance
How to circles mensurate.

and another one also to 30 decimal places (written by Michael Shapiro)
Now I will a rhyme construct By chosen words the young instruct.
Cunningly devised endeavour, Con it and remember ever. Widths of circle here you see.
Sketched out in strange obscurity.

Should you have a repressed desire to experience a brain implosion, try these: Near A Raven, an Edgar Allen Poe-esque poem which currently holds the record for longest pi mnemonic, at 740 digits.Cadaeic Cadenza, a short story (!) which is longer still at 3835 decimal places, and has additional constraints.

Angles

Complementary angles form 90 degreesComplementary angles form a corner.
This video shows three methods to help you remember complementary and supplementary angles.
Method 1: In the alphabet, the letter "C" for complementary comes before the letter "S" for supplementary and in the number line 90 comes before 180.
Method 2: A corner is 90-degree angle and a Corner is Complementary.
A straight angle is 180 degrees and Supplementary angles are Straight angles.
Method 3: The word complementary has one p, the word supplementary has two p's. We can take one p to represent 90 and two p's to represent 180.

Angle Properties (Math Song)
In geometry if you want to fare well
You need to know that parallel lines
They never touch
They're always the same distance apart
It's as if they don't like each other much

And there's only one thing that comes between them
Yes a line that passes right through each of them
It's called the transversal
And it has several angle properties
Just like these
